I'm trying to compile sources using ninja, unfortunately I'm getting the error bellow. Any idea? I can use cmake (CMakeLists.txt file in src folder), but I'm not sure this is for the production use. And finally, could you please provide me w/ the .pc file? Thanks a lot.
According to the readme you first need to install the libpng-dev or libpng-devel package depending on your linux distro:
Install the dependencies
On Debian:
for the encoder/decoder: sudo apt-get install libpng-dev
for the viewer: sudo apt-get install libsdl2-dev
On Fedora:
for the encoder/decoder: sudo dnf install libpng-devel
for the viewer: sudo dnf install SDL-devel
On Ubuntu:
for the encoder/decoder: sudo apt-get install libpng-dev make pkg-config
for the viewer: sudo apt-get install libsdl2-dev
You may want to use JPEG XL instead.
FLIF development has stopped since FLIF is superseded by FUIF and then again by JPEG XL, which is based on a combination of Pik and FUIF. A royalty-free and open source reference implementation of JPEG XL is available on GitLab. For more information, see Jon's JXL info page or visit the JPEG XL Discord server
My apologies, I should write at the beginning that I'm using Ubuntu 18.04 w/ installed libpng-dev 1.6.34. It's weird, because I can build flif, gif2flif and libflif.so.0 using make (makefile is included in the source code) - so ninja is not fully configured. Anyway, I'll use JXL.. Tx
